Fig. 96 is a filter support adapted to the rapid passage of liquidsin filtration; it, however, requires to be used in connection withan open or wide mouth receiving vessel or a funnel, otherwise theliquid might not be perfectly collected as it passes downwards. In filtering very volatile liquids, particularly in hot weather, somecontrivance must be resorted to, to prevent evaporation from thewide surface exposed, while, at the same time, the escape of airfrom the receiving vessel must be provided for. The drawing heregiven, Fig. 97, from Mohr & Eedwood, represents an arrangementof the kind. The glass funnel is fitted by a cork into the receivingvesse
